The axe is a weapon that is one of the melee weapons used in Madness Combat. First appearing in Madness Avenger, the axe was used twice by Hank against his enemies, who were also seen armed with it. That particular design had a cut-out blade, possibly to lower the weight.

A different version of the axe was later seen with dark cloth wrapped around its handle and a larger blade. Both versions, though, had a triangular blade on the back. It was used in Incident: 001A by Hank to throw some l33t agents into a giant blender before finally being thrown at a Mag Agent: V2.

The older version of the axe can be used in Madness Interactive, and can be a one-hit kill to enemies, depending on what perks you pick while playing. It is also a blade featured in Madness: Project Nexus.
